“There were four pieces [of glass] that got into my lower back. … I was bleeding,” Lopez Bianchi said.

She couldn’t immediately retrieve all of the centimeter-sized glass shards from her back — and said the $235-per-month gym should have been more careful.

Her $100,000 Manhattan Supreme Court lawsuit notes that she is “an international model who must maintain a pristine appearance for her work.”

Lopez Bianchi says she works out at the gym “virtually every day.” She claims the incident was troubling because five days before she was hurt, she told Equinox about broken glass on the floor near a bathroom adjacent to the exercise areas.

When she followed up her verbal complaint with an email, an Equinox manager thanked her.
